As aresult railwayrolling stockI now'in com- Ymon useis generally, extremely'noisy in op-A 5 eration,;in:strong-contrast tothelmodern* buses*andautomotivetypesof vehicles.- f f;

n Wehavefound that railway rolling stock,"v and particularly electrically 4drivenvrail cars -need notpartake of the heavyiconstructions now'. generally employed, and that it is entirely feasible to construct a railcartru'ck ,havingade'gree of resilience` in theconnections betweenfthe Yvarious parts that serve to. support the car body and tovery .greatly reduce Vthe weighty of the car. The reduction in f weight results in more silent operation,

even in the absence of the resilientbonnec tions between the supportingv elements'of the car body. j VHowevergg such]k resilient interconnections serve. to further..

lessA noisy operation of' railway rolling stock.V 'zlnprior rail car braking constructionsvfit v" t etvve e 1 1 the-supporting parts of the railxca'r v and body constructionheretofore not relu brake j shoes on swinging link mechanism which 'swings the shoesonian .arcuate path ,into engagementwiththe flangedperipheries ofi the wheels. Y With such mechanisms the brakes are irregularly applied,-wear unevenly, andtend to'grip and lock `against the wheels. -.A`s v:aj-result considerable poweris required toifree thelocked brakes in starting a car or l .train moving after kthe brakes have been ap plied, and the ybrake .shoes and vWheels wear "unevenly requiring costly service and replacements, 4 while vample material still ,remainsin i The u nevenness of `brake application tendency to lockagainst the `wheels when the brakesfare appliedy in the prior constructions iV the shoesfor long service if the wear'had been Y ,evenlydistributed H results inineHicientlbraking, noisy operation,

a 'substantial wasteof power re(`1uiredto.iniv

practicable safe speeds of operation, and reduced sizesrof the trains that can be handled by locomotive and powercars.

Accordingly a primary objectief the present invention is to provide novel braking arrangements for railway rolling stock in which the brake shoesare uniformly, evenly and effectively applied upon application of the braking power,and instantly and positively released when the application of braking power is discontinued,'and in which the tendency for the brake shoes to chatter and lock, and irregular Wear of the shoes and wheels is completely eliminated.

Another objectof our invention is to providebrake Yconstructions for railway rolling Ystock which Vreduces 'materially the .amount ofV power required to handle railway rolling stock permitting operation at-higher speeds, and of larger size trains; assures uniform application of braking power on each wheelV with attendant smoother operation andin-V creased comfort and safety to passengers and freight; and assures maximum uniform life of brake shoes with minimum maintenance and service. llVhile our improved-'braking arrangement was 'devised especially vfor use inthe improved electrically driven trucks hereinafter disclosed, it is applicable toall forms of railway equipment at present in use,

l .either as Vinitial or replacement equipment and application thereof to all types of railway v `rolling stock is contemplated as within the yscope of the present invention 'as will more fully hereinafter appear.

Still another object of this invention is to provide a rail car truck construction of rela-v tively light weight,'compared to the heavy constructions now' in general use, 'and embodying flexibleV and resilient interconnections between the running Vgear and the body 'of the car, andv between the various parts of the running' gear, that will enable the car to be operated silently, without causing ir'ieificientV or undesirable operation of the'driving means .or braking means when the parts of the vehicle move relative to each other.

A further ob;l ect of the invention is to provide a rail car including a truck in which leaf spring assemblies are relied upon to space the axles apart and to resiliently connect them tov Athe frame members, and in which the wheels as well asthe connections'between the springs and the axles are provided with cushioning elements, minimizing, so far as possible, metal to'inetalcontact at the points of connection, providing a construction that opcrates silently over even poorly aligned tracks,.and that will possess superior riding `'qualities in view of theabsorptionof the vi- 'brati'on of the parts of y the body in theresilient cushions.

Y i A still furtherrobject the'invention to provide a rail'car including truckshaving a high degree of flexibility and light weight,

ly driving the axles are mountedon the bolf ster independently of the axles so that free movement of the axles with respect to .theV

bolster is permitted.

f VStill another object of the 'invention is to provide a rail car havinga truck consisting of holsters and axles held in spaced relation Y by leaf spring assemblies'in which axlesware individually driven by motors that 'each' areV attached to the side oftheV bolster'remote from that nearest toY the Ydriven axle, whereby longer drive shafts may be employed to couple each aule and. its motor permitting substantialv movement of the Kaxle with respectV tothe motor without causing the driveshaft to move through large angles when the axles Y move with respect tothe bolster, sincethe amplitude of angularl movement of thev shaft is a function of the length'ofthefshaft.

A Vfurther object of. the invention' is to ported by a truck having a high degree Vof flexibility and capable of swinging with respect to the car body about axes thatare substantially vertical, in which the wheels ofthe truck are provided with brakes,"the application of whicn is substantially unaffected byyirtue of the wheel movement p'erinitted because of the Vfact lthat the construc-V 'tion'is relatively flexible.

A still further obj ect ofthe inventionis to provide a rail car, supported drive trucks v that are pivotally connected tothe body Vfor movement about verticalaxes in which emergency brakes are provided on the motor shaft carried by the truck holstersV and in which the mechanism. for operating the brakes is so provide a rail car, the body 4of which is sup# associated with the truck, that the trucks are free to swingas the car rounds turns withoutV introducing disarrangement` ofthe braking mechanism that may result inanimproper application `of the brakes caused by changes position of the parts as the vehicle is rounding a curve. Other objects of the invention will appear Vas a description thereof proceeds and from the terms of the appended claims.'V Ars shown in the drawings: Y Figure l is .top plan view part/lyV broken awa-y of a preferred truck construction em-V bodying our invention Figure 2 is a longitudinal'section substanfV tially along line vrilll of Figure l, and including the Central bolster pivotal connection theV introduction offfactorsV with -wliich'the truclrconl truction'mavbe difl rectlyassociated.

Secured as by bolts 48 to :the rhorizontal flanges of members 46, as well as to plate 47, adjacent each end of plate 37, are angular plate members 49 each embodying laterally spaced vertical portions l and 52 and a horizontal portion 53 integrally connecting said vertical portions.

The opposite ends of plate 37 are disposed intermediate plate 47 and portions 53 of -plates 49 and disposed on the ,lower side of plate'37 adjacent each end thereof, between the plate and the portions 53, are'yielda-ble, preferably rubber, blocks 54 and disposed above plate' 37 is a transversely continuous cushionbloclr 55. 'A bolt 56 projects vertically through aligned apertures in opposite ends of plate 37 as well as blocks 54 and 55. By this construction plate 37 is connected with 4the-vehicle body 'in such manner that'it is capable of yieldable vertical movement. To reduce friction to a minimum suitable antivfriction plates 5 7 are disposed between walls andthe vertical flanges of member-s 46, as is clearly indicated in Figure 2, which antifriction plates may be extended or .additional plates provided between flanges 52 of plate 49 and walls 36 of plate 37, as indicated at 58 'in Figur'ev4.

Y It will accordingly be seen that a yieldable pivotal connection between bolster l and floor 22 ofthe car body to permit alinement of Ywheels on curved sections oftrack is provided. and that said connectionsfurther pro:

to the bolster ll Vas the entire assembly con-l lined within plates 49 is bodily movable with the `vehicle body, but plate 37 due to the cushioned blocks 54 and 55 is capable vof yieldable vertical movement', whereby the car body may move laterally a limited amount V on rocking members 38', but-due to the fact that platel37 can-move vertically against the yieldable resistance of bl-oclrs `gjtheside `movement of therbody will not 'beacconi-KV panied byvertical raising thereof.
